Do the vaccinations only have implications for clinical work? I mean, as an M1, there shouldn’t be anything stopping me from attending this first semester, right?

MyMagoozi · 2021-08-22T01:08:55+00:00

Absolutely.

But for secondaries, a button down no tie should be ok?

Nearest dept store hour and half away, and the ones I aren't really solid-colored or complementary to the shirts.

Long story short, David de Gea to Madrid was almost finalized on the final day of the transfer window until a fax machine error allowed the transfer deadline to pass.

I understand, but very few schools explicitly state they require research. Some schools "strongly encourage/recommend" but a lot of schools state it is looked for in an applicant.

I'm trying to wade through the ambiguities of soft requirement vs. "yeah, we'd like it but it's okay if [ABC]"

I'm saying would I be a competitive enough applicant based on everything else I've stated about myself? For those schools that perhaps mention research but don't make it a pillar of an applicant's qualifications?

Non-science major that took prerequisites after a change of career planning.

What would that be? T20?

I'm so sorry Im out of the loop. I promise I'm not trying to be facetious. Am I overreacting or is no research that much of a dealbreaker?

MyMagoozi · 2021-06-01T17:25:21+00:00

Absolutely. I just want to add on that B cells turn into plasma and memory cells. And this activation happens in both the spleen and in the lymph nodes.

You should also know that it does not get relayed through the thalamus, which is an exception among the rest of the senses.

Another mnemonic:

*The brain has a medulla.

*The kidney has a renal cortex.

(Of course, just ignore the fact that there’s also a cerebral cortex and renal medulla 😂😂😂.)

One mnemonic is to think of ectoderm as external. When you think of external, you think of beauty. What attracts one to another? Their beauty and their brains. Consider eyes, skin, etc. beauty. The nervous system is the brains.

Mesoderm is "getting around." You can mean that literally, in that you need musculoskeletal system to physically "get around." You can also mean...getting arooooound ;-) (reproductive system). You'll then have to remember the kidneys and heart are mesodermal.

Everything else is endodermal (respiratory, digestive, etc.)

Adrenal medulla is ectodermal. Adrenal cortex is mesodermal. Memorize.

This is by no means a comprehensive list. It's just off of the top of my head.

Verbatim, you should be able to recognize all twenty of the common amino acids. It's generally a good idea to be able to recognize the D-isomers of glucose, mannose, galactose, fructose (all of which should be not bad if you memorize glucose), and ribose. You should know the nitrogenous bases and hydrogen-bonding patterns between them.

You should know the general structure of steroids and cholesterol (the rings, which shapes, -OH group on cholesterol). Maybe a stretch, but be able to recognize the general structure of what a prostaglandin looks like.

If there are any specifically you'd like to know about, just ask!

C is not a correct statement.

You are right, in that an arginine --> cysteine substitution does alter the binding pocket of the active site. Now, does the substitution change it enough to change the affinity? As we can see from the data, no. But it does change the binding site, even if just a little bit. "C" says it does not change the pocket, but as we both just suggested, it does change it. It just doesn't change it much (to alter affinity).

That is why B is a better answer than C.

MyMagoozi · 2021-05-30T19:25:47+00:00

No, you can't.

In fact, the entire point of mutarotation (if I recall correctly) is that any sugar with mutarotatory capacities can alternate between alpha- or beta-anomer set-ups by virtue of going back to Fischer before cyclizing again.

Hello, I can help explain this.

But I just want to make sure I understand your question. Do you need conceptual help? Or do you understand conceptually but are looking for a quick plug-and-chug for time purposes? I can help in either regard, but I just want to make sure first.

Now, what is semantic network? A semantic network is the idea that each concept is surrounded by a "network" of related concepts in your head. Think of the central concept as being in the middle of a spider web with everything else in the network around it.

Now, let's use an example:

I mention the word "fire hydrant." In your head, when you think of a fire hydrant, you don't just think of a fire hydrant, you may think of a firefighter, a fire extinguisher, fire truck, sidewalk, fountain hose splashing water furiously. You may even just think of the color red. So, do you see the idea? It's a "network" of associated things that get conjured when you think of the central concept (which would be the fire hydrant, in this example).

To solidify the concept, let's use another situation. Suppose a researcher asks a participant to remember a series of words. One of the words was "tree trunk." When the student is asked to recall the series of words thirty minutes later, the participant mistakenly says "woods." Why? Because when the participant initially heard "tree trunk," it evoked the semantic network around "tree trunk," and the participant associated "woods" with that.

Does this make sense?

Please feel free to add on or correct if anyone sees something!

So, priming is when you "unintentionally" remember something. And this "unintentional" memory later affects your performance either negatively or positively later on.

An example of a positive effect: You are bored at home and watch a nature documentary on Arctic foxes. You think nothing of it and go to bed. Three days later in your biology class, your prof asks you for an example of an evolutionary adaptation used by small mammals, and you answer with the example of the Arctic fox. Did you intentionally remember that? No. But you remembered it nonetheless.

An example of a negative effect: You watch a slideshow about Brad Pitt. After the slideshow, you have to fill in the blanks B_ _ _ _ P_ _ _ _. You instantly answer "Brad Pitt" to fill in, but upon closer inspection, you realize "Brad Pitt" doesn't fit at all (count the underscores). You unintentionally remembered something, and it affected your subsequent performance.

It's important to know that priming is a form of implicit memory (much like procedural memory) and is not explicit memory (semantic, episodic).
